Gas High Speed Centrifugal Spray Dryer LPG Versatile Durable

Product Specification

High-speed centrifugal spray dryer operating procedures:

Ensure that all pipe connections have appropriate sealing materials and good sealing functions, without running, bubbling, dripping, or leaking.
Check whether the equipment and pipelines are blocked or leaking. If there are any questions, they should be dealt with in time.
Check whether the rotation direction of the centrifugal fan is correct and whether the conditioning butterfly valve at the outlet is open.
Check whether the spray head on the top of the drying chamber is firmly installed to prevent air leakage.
Check whether the temperature of the motor bearing is normal and whether the anchor screws are loose.
After turning on the electric heater, check whether there is leakage and preheat the barrel. The temperature is controlled within the range of 180℃-220℃.
Adjust the frequency of the atomizer to make the nozzle reach a high speed.
‌Operation steps‌:

The air enters the air distributor at the top of the dryer through the filter and the heater, forming a spiral hot air that enters the dryer evenly.
The liquid is pumped from the liquid tank through the filter to the centrifugal atomizer at the top of the dryer to form extremely small mist droplets.
The liquid material and hot air are in contact with each other, the water evaporates quickly, and the finished product is dried in a short time.
The finished product is discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan.
‌Safety precautions‌:

Before operation, make sure that all safety equipment such as emergency stop buttons are in a usable state.
Operators should wear appropriate protective equipment such as work clothes, gloves, goggles, etc.
During operation, pay close attention to the operating status of the equipment. If there is any abnormality, stop the machine immediately for inspection.
Following these operating procedures can ensure the safe and efficient operation of the high-speed centrifugal spray dryer, while ensuring the quality of the finished product‌.

‌The specifications of high-speed centrifugal spray dryers mainly include the following aspects:

‌Working principle‌: The working principle of high-speed centrifugal spray dryers involves hot air passing through filters and heaters and entering the top of the centrifugal spray dryer. The hot air enters the dryer in a spiral shape and evenly. The liquid is pumped from the liquid tank through the filter to the centrifugal atomizer at the top of the dryer, so that the liquid is sprayed into extremely small mist droplets. The liquid and hot air are in contact with each other in parallel, and the water evaporates rapidly. It is dried into a finished product in a very short time. The finished product is discharged from the bottom of the drying tower and the cyclone separator, and the exhaust gas is discharged by the fan. ‌Technical parameters‌: The specific technical parameters may vary depending on different models and configurations, but generally include the following aspects: ‌Water evaporation capacity‌: For example, the water evaporation capacity of the LPG-200 centrifugal spray device is 200kg/h‌. ‌Processing capacity‌: This depends on the type of material to be processed and the expected output. ‌Initial and final moisture content of the product‌: This is directly related to the degree of dryness and quality of the product. ‌ ‌Hot air inlet temperature‌: For example, the hot air inlet temperature of LPG-200 is about 340℃‌.
‌Hot air outlet temperature‌: Usually maintained at 90-110℃‌.
‌Material‌: All made of stainless steel 304 to ensure the hygiene and quality of the product.
‌Control system‌: Including temperature control, flow control, etc. to ensure the quality and production efficiency of the product.
‌Application range‌: High-speed centrifugal spray dryer is suitable for generating powdered and granular solid products from solutions, emulsions, suspensions and paste-like liquid raw materials. It is particularly suitable for occasions where precise control of particle size distribution, residual moisture content, bulk density and particle shape is required‌.

‌Equipment features‌:

Fast drying speed, generally only 5-15 seconds, with instantaneous drying characteristics, suitable for drying heat-sensitive materials.
The production process is simplified, the operation and control are simple, and it is suitable for continuous control production. Liquids with a moisture content of 40-90% are dried into powder at one time to improve product purity.
The product has good dispersibility, fluidity and solubility. The particle size, looseness and moisture content of the product can be adjusted within a certain range by changing the operating conditions, and it is very convenient to control and manage.
In summary, the specifications of the high-speed centrifugal spray dryer cover its working principle, technical parameters, application range and equipment characteristics. These specifications jointly ensure the efficient operation of the equipment and the high-quality output of the product.
